Abstract
In an OLED there is a reflectivity influencing layer (27) which is preferably semi - absorbent and in embodiments is dark coloured or black which is formed of a sublimable organometallic compound. The reflectivity influencing layer is formed between an electrode (29 or 22) and a light-emitting layer (25).
